Detailed explanation-1: -Behavior can also be shaped by natural selection. Behaviors such as birds’ mating rituals, bees’ wiggle dance, and humans’ capacity to learn language have genetic components and are subject to natural selection.
Detailed explanation-2: -Selection will favor an altruistic act if the benefit of the act (in terms of indirect fitness) exceeds the cost of the act (in terms of direct fitness). When individuals are more closely related, they have a greater relatedness (r) and altruism is more likely to occur.
Detailed explanation-3: -To the extent that behaviors are controlled by genes, they may evolve through natural selection. If behaviors increase fitness, they are likely to become more common over time. If they decrease fitness, they are likely to become less common.
Detailed explanation-4: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
